The problem

Your newsletter takes all day. Or it doesn't get written at all.

You sit down to write and hours later you're still not done. So you skip a week. Then another. The audience you have stops trusting you. The audience you could've built never finds you.

How it works

From idea to audience in three steps

1

Teach it your brand

Share three samples. Flyletter builds a complete voice profile so every issue sounds like you.

2

Pick a topic and go

Bring an idea, take a suggestion, or let Flyletter decide. Get a publish-ready draft in your voice.

3

Review and promote

Refine anything by chatting with Flyletter, then generate weeks of social posts to promote with a click.

The team

Six roles, one newsletter pipeline

Give Flyletter a topic. Six content specialists plan, research, structure, draft, edit, and illustrate your newsletter. You review and send.

What our users say
“Flyletter writes the issue and the social posts in the time I used to spend on one channel alone.”
Andrew Lane

“Fashion content has its own language, and most AI tools produce generic style content. Flyletter captured my voice. The way I phrase things, the references I use, the words my audience knows me for.”

“I tried writing newsletters in ChatGPT for months. Every issue meant a multi-prompt sequence and hoping the output didn't drift. Flyletter has the content team built in.”

From the founder
Evan Tarver, Founder of Flyletter
“I've been writing for years. Built and sold a content business, ran growth at a startup, self-published books for fun. But I couldn't keep a consistent newsletter. I spent months prompting ChatGPT and Claude. It took longer than just writing it myself. So I built Flyletter for me, and now for you.”

Questions

Frequently asked questions

ChatGPT and Claude are general assistants. Flyletter is a newsletter system: a brand profile that learns your voice from three writing samples and a content team that runs the pipeline every week. The brand profile compounds. Every issue gets closer to sounding like you. ChatGPT starts from zero every prompt.
That depends on the quality of the three writing samples you share. The brand profile captures voice mix, tone, sentence rhythm, vocabulary, structural patterns, and the words you'd never use. The first newsletter you generate is the proof. Read it and decide.
Share three writing samples and Flyletter compiles what is measurably true about how you write into a structured brand profile. Every specialist on the team reads it before doing their job. The Strategist picks angles in your voice. The Writer drafts in your voice. The Editor polishes in your voice. Same profile, every issue.
On Pro, Flyletter sends newsletter drafts to Beehiiv or Kit. Kit connects with an API key, and one click puts the draft in your Kit account. Beehiiv drafts go through Claude and Beehiiv's own connector, so the draft is built in your usual template. Two connectors need a paid Claude plan, since Claude's Free plan allows one. For Substack, Ghost and other platforms, you copy the text into your editor.
Yes, with Flyletter's Claude connector, on Pro. It runs the whole workflow from a chat: outline and write your newsletter, plan, write and publish your social posts, write emails and pages in your voice, and update your brand profile as you go. Newsletters and posts you write in Claude run on your own Claude account, so they never count toward your plan. The connector works on every Claude plan, Free included.
You do. Your writing samples, your brand profile, and every generated draft belong to you. Your profile is not used to train shared models or accessible to other accounts. If you cancel, you can export everything before you go.
